Idk what to do😞

My boyfriend and I have been arguing since friday. We broke up on saturday and i was fucking heart broken so ofcourse i tried to fix it well everything was actually amazing till just now when he decides that he doesnt think he wants to be with me anymore. We had sex today? Why why why would he do this to me. Im sitting here crying because hes the only person on this earth who i want to spend my life with. I feel like love like this doesnt happen often. I love him more than i love anything on this earth. He makes me want to be a better person everyday. I have severe depression and anxiety and he helps me so much. I feel so empty already that i cant even imagine what these next days are going to be like. Im honestly hoping that i dont even wake up in the morning because my life is meaningless without him. I have no idea what to do
